<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.7/jquery.min.js"></script>
<script type="text/javascript">

$(document).ready(function() {

 alert('The first class item in the body tag that ends with aspx is ' + 'exampleaspx');

});

var currClass = $(body).attr("class");
var newClass = currClass.replace(/\s[^\s]*aspx|^[^\s]*aspx\s+/,"");
//alert(newClass);
$('body').attr("class", newClass);

This should find it for you:
var m=$('body').attr("class").match(/[a-z-]+aspx(\b|$)/i);
var myClass = m?m[0]:'';
